IPC: F02D41/14
Filed: 2003-05-20
Abstract: <P>PROBLEM TO BE SOLVED: To improve exhaust emission by compensating fuel shortage due to adhesion generated during suspension of air fuel ratio feed back control after return from fuel cut and quickly returning condition of the inside of catalyst into an appropriate emission control window.  <P>SOLUTION: Quantity of injected fuel is increased by adhesion correction quantity after fuel cut during a period between return from fuel cut and start of air fuel ratio feed back control. If it is determined that actual air fuel ratio gets in a roughly rich condition based on output of a front air fuel ratio sensor or it is determined that a condition of the catalyst gets in a roughly rich condition based on output from a rear air fuel ratio sensor, fuel adhesion correction is completed. Consequently, adhesion fuel lost due to fuel cut is compensated and the inside of the catalyst under excess oxygen condition can be quickly returned into the appropriate emission control window, air fuel ratio is quickly normalized and purification rate of the catalyst can be quickly improved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: F02P5/15
Filed: 2003-05-30
Abstract: <P>PROBLEM TO BE SOLVED: To suppress generation of undertone noise in an exhaust gas passage without deteriorating the early warm-up of a catalyst by ignition delay, by appropriately stopping secondary air supply during deceleration.  <P>SOLUTION: When ignition delay control is executed in a middle of warm-up of an internal combustion engine 1, secondary air is supplied into the exhaust gas passage 12 via a secondary air control valve 42 and three way catalyst 13 is early warmed up. At that time, if deceleration condition is detected and intake air pressure PM detected by an intake air pressure sensor 22 becomes lower than a determination threshold, secondary air supply is stopped. If the determination threshold is set, for example, in a more positive pressure side than that at a time of not executing ignition delay control, timing of stopping secondary air supply can be increased during deceleration. Consequently, the three way catalyst 13 can be activated with early warm-up while suppressing murmuring noise generated at a time that unburned HC burns in the exhaust gas passage 12.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
